l'Claim. 1

This invention relates to improvements in attachments for firearms.

An object of this invention is to protect the rifiing in a gun barreladjacent the outer end thereof by preventing the portion of the guncleaning rod intermediate its ends from engagement with the rifling ofthe barrel during cleaning operations, as the cleaning rod isreciprocated and/or twisted.

Other objects and features will become apparent in following theillustrations.

In the drawings:

Figure 1 is a fragmentary elevational view of the outer end of a gunbarrel, portions being broken away in section to illustrate detail ofthe attachment on the gun barrel;

Figure 2 is a side view of a fragmentary part of a gun barrel with theattachment applied at the end thereof;

Figure 3 is an end view taken substantially along the plane of line 33in Figure 2;

Figure 4 is a sectional View taken substantially on the line 4--4 ofFigure 2; and

Figure 5 is an exploded perspective view of the elements which form theattachment.

In cleaning a gun barrel, it is the usual practice to reciprocate aramrod or cleaning rod in the bore of the barrel, said rod having awadding at the end thereof. Periodic cleaning is necessary in order tomaintain the firearm in proper condition.

During the cleaning operations, it is not infrequent that the rod,intermediate its ends, engages the inside surface of the barrel and itis not uncommon that this engagement causes injury to the rifiing at thevery end of the barrel.

The instant attachment prevents this contact of the rod with the riflingof the barrel.

The outer end portion of a gun barrel in is illustrated in the drawingsand has a part of the conventional structure a gun sight element [2rising from the upper surface thereof. The rifling [4 in the barrel ispurely conventional in nature and typical of certain types of firearmswhich rely on the twist of the projectile to direct it accurately. v

The attachment consists of a clamp l8 which is substantially c-shapedand is adapted to extend around only a portion of the gun barrel.

2 without interference caused by the presence of the element l2.

Means for releasably fastening the clamp in place on the outer end ofthe gun barrel is provided. The illustrated means consists of a screw 24which has a knurled head and which is disposed in the thickened endportion iii of the clamp 16. The screw is passed through an internallythreaded passageway and is adapted to contact the outside surface of theend of the barrel [0.

A pair of spaced threaded openings 26 and 28, respectively, are providedin one face of the clamp l6. Screws 30 and 32 are disposed in theopenings 26 and 28 after passing through slots 34 and 36 which areformed in the collar 38.

The collar 38 rests against the outside surface of the clamp I6 and isadapted to overlie a part of the end of the gun barrel [0 This collarhas an opening 40 with a slip 42 rising from the collar and disposedaround said opening. The opening 49, lip 42, and collar 38 form a guidefor the cleaning rod, preventing it from coming into contact with therifling of the barrel after the cleaning rod has been inserted throughthe open end of said barrel. The screws 30 and 32 in the openings 28 and26, after passing through the slots 34 and 36, are used to adjustablyfasten the guide to the clamp.

Reference to Figure 4 shows that there are two outwardly divergingsurfaces 50 and 5| on the inside of two legs of the clamp which engagethe outside surface of the gun barrel. These the barrel so that thedevice may be used on gun The outer ends l8 and-20 of the clamp l-S arebarrels having different thicknesses and widths. The barrel contactingsurfaces 50 and 5| and the inner end of the screw 24 may be providedwith a cover. for example, rubber, felt or other fabric, to prevent thepossibility of abrasive action of the contacting surfaces on the gunbarrel. Having described the invention, what is claimed as new is: r

' For use with the barrel of a gun which is provided with rifiing in itsbore, the improvement comprising a clamp adapted to be fastened at theend of the barrel, a cleaning rod guide which includes a collar with anopening substantially the same diameter as the bore, a fastening elementsecuring said collar to the outer face of said clamp to thereby mountsaid guide at the said slot so that said collar may be adjusted withrespect to said clamp.
